Axial Piston Pump In Engineering: Novel Overview
Axial piston pumps release separate amounts of fluids into downstream piping. Each piston compartments creates
a pressure rise and fall in the system piping, these pressure changes form a sine waves. This sine wave signifies the
instantaneous flow rate of a single chambered and the mean flow rate of this pump is the average discharge per
revolution. As increasing the number of pistons of an axial piston pump, that’s means generating additional sinusoidal waves
offset by time. As a result, the pressure fluctuations are reduced and decreasing amplitude of flow and pressure ripple.
Hypothetically an unlimited number of pistons will completely remove release pulsation. Number of pistons varies by the
type of pump construction. Commonly deal with piston pumps between one and eleven pistons, but in the industry where
axial piston pump are designed a certain amount of confusion exists on the part of most designers regarding the trade-offs
between designing a pump with an odd number of pistons and designing a pump with an even number of pistons. This
proposal explores the flow and torque ripple which resulting from an axial piston pumps showing that the similarity between
shafts torques and flow pulsations (ripple). explaining the relationship between the number ofpistons and discharge
flow-torque ripple by using graphical and numerical methods and finally establishing a numerical formulae relate
between number of pistons and flow- torque pulsation factor and comparing the results of formulae of this present
proposal with another previous work.
